A man walks across the beach. The sky’s getting dark as he steps barefoot into the waves. A shark swims into view, its fin standing straight. The shark says, get out of the water, it’s my place. The man ignores the shark and keeps walking.
The shark returns a while later. The big fish says to the man, get out. Once again the man ignores the shark. It’s too deep to walk so the man swims.
The shark returns a third time. The shark says, if you don’t go back you’ll die. The man faces the shark and says:
If I go back, I’ll drown.
